Typically, Visualization is done after the data is gathered or simulation, but a research study by Donald Appleyard back in 1969 flipped this around by turning the visualization into the data gathering step.

Another chart plotted peoples’ perception of their “home territory” on the 3 different streets. On the heavily traffic street, residents drew red rectangles which shows their apartment, or in some case, their whole building, as being their home territory. In contrast, on the lightly traffic street, most of the people are defining their entire street as their home territory, with some people highlighting their building or a slightly larger area.

Now, he did go with more traditional methods, plotting connections between neighbors to show how interconnected an area of light traffic is compared to high-traffic.    It’s an interesting study with impressive results.
